Has anyone had the issue, when they own mac hardware, that when they install sound drivers it causes kernel instability, until you upgrade the kernel beyond the LTS recommended, then when installing VBox, due to OS instability with the headers, you need to downgrade the kernel to LTS, causing sound driver instability?
What distro are you running? Perhaps they also offer the VirtualBox modules as DKMS, theorically working with whatever kernel you are using?
Truth be told the Vbox kernel module rigmarole eventually prompted me to try virt-manager instead.
It does some things different and ends up being a touch less user-friendly, but the learning curve is not too big. Give it a spin, you might like it!
I know GNOME also has a very polished app called “Boxes” that uses the same tech virt-manager does. I haven’t used it myself but it might be nice too.
